CompTIA Security+ (SY0-601) — Question 205

A new security engineer has started hardening systems. One of the hardening techniques the engineer is using involves disabling remote logins to the NAS. Users are now reporting the inability to use SCP to transfer files to the NAS, even though the data is still viewable from the users’ PCs. Which of the following is the MOST likely cause of this issue?

Answer options

• A. TFTP was disabled on the local hosts.
• B. SSH was turned off instead of modifying the configuration file.
• C. Remote login was disabled in the networkd.conf instead of using the sshd.conf.
• D. Network services are no longer running on the NAS.

Correct answer: B

Explanation

The correct answer is B because SCP relies on SSH for secure file transfers. If SSH is turned off, users will be unable to use SCP, even if other access methods are still functional. The other options do not directly affect the ability to use SCP for file transfers.
